mx800d screen glitch

[shsilian]

The two screens of mx800d are not bright, and it is preliminarily judged that the power board is faulty。

Where can I buy this power board？

The power board model is 

Delta APDP-416A1 Replacement Switching Power Supply Unit 2955028104

Replaced one of the control chips on the main board of the power supply, and it can be used。

Can't you see it when you zoom in? I found an electronics repair shop to fix it for me.
